Floor Leather Paving Adhesive Solutions

Strong bonding, environmentally friendly

JS-3160 two-component polyurethane structural adhesive is a solvent-free two-component adhesive d on polyurethane. Component A is composed of polyhydroxy compounds, while component B (curing agent) is isocyanate. When used, the two components are mixed in a certain proportion. The mixed adhesive will form an elastomer through chemical reaction. This product has no corrosion, low shrinkage rate, and fast curing speed.

JS-3160 two-component polyurethane structural adhesive is suitable for bonding surface treated metals, synthetic materials and hard foam. It is mainly used for sandwich plate assembly, floor and carpet bonding, and can also be used for industrial potting coating to heat electronic components and waterproof and damp proof bypass.

Advantages of the plan

Main features:
1. Long opening time: 50-70 minutes, and not sensitive to temperature, ensuring sufficient operating time during construction;
2. After starting the reaction, the curing speed is fast, and the hot air gun welding program can be entered within 3-4 hours.

Product advantages:
1. Excellent stability
By utilizing the characteristics of polyurethane's water absorption and low swelling of water absorbing colloids, polyurethane sealant has a good stability performance of non shrinkage after curing, especially at corners. Its flexibility and stress absorption effectively reduce the expansion and contraction of the bonding substrate, ensuring overall flatness.

2. Excellent durability
After repeated comparative tests, it was found that it is heat-resistant (90 ± 2) ℃ for 500 hours; (120±2)℃,24h; Resistance to humidity and heat; High and low temperature cycling; Water resistance; Resistance to artificial aging; Under aging conditions such as salt spray resistance. Tensile strength (MPa); Tensile retention rate; Shear strength (MPa); Shear retention rate; Excellent performance in various aspects.
